Space Tubes
In 2011, NASA produced a material that absorbs on average more than 99% of the ultraviolet, visible, infrared, and far-infrared light that hits it. NASA’s so-called “super-black” material is based on a thin layer of multi-walled carbon nanotubes.
Tiny gaps between the nanotubes collect and trap light. The carbon absorbs the photons, preventing them from reflecting off surf... » read more
